Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What keyword would you use to ensure a variable is not optimized away by the compiler when it can be changed unexpectedly?

💡 Hint: Think about variables that might change due to external factors.

Question 2 Easy

Write a line of code to set pin PD6 as an output.

💡 Hint: You are manipulating the Data Direction Register.

Question 1

What command sets a pin as an output in C for AVR microcontrollers?

DDRD |= (1 << PD6);
PORTD ^= (1 << PD6);
DDR |= (1 << OUTPUT);

💡 Hint: Focus on the DDR which is responsible for pin direction.

Question 2

True or False: The volatile keyword is used for variables that are rarely modified.

True
False

💡 Hint: Consider the behavior of variables in different contexts.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Write a C/C++ code that sets up an interrupt to toggle an LED when a button is pressed. Ensure to declare the flag variable correctly.

💡 Hint: Remember to set up the correct microcontroller registers to handle the button press.

Challenge 2 Hard

Discuss how you could optimize your code if your microcontroller has limited memory resources while also needing to handle multiple LED states.

💡 Hint: Consider the impact of your data structures on memory allocation.
